What is the range of the function y = 3x – 2?

-2
0
2
3

The correct answer is: 3

The range of a function is the set of all possible outputs or y-values. In this case, the function y = 3x - 2 is a linear function with a slope of 3 and a y-intercept of -2. This means that for every input value, the output will be three times the input value minus 2. Therefore, the range of this function is all real numbers except for 3, which is the slope. The choices A, B, and C are not correct because they each represent a single value, while the range of a function can contain multiple values. Additionally, they do not consider the slope of the function, which is an important factor in determining the range.
